In accordance with the conservation energy law it follows that the incident radiant power onto object must be equal to the sum of the absorbed, transmitted and reflected power. This can be characterized by the relation: + + = 1 (1)where absorption, the ratio of absorbed radiation power to incident power; is the transmittance of the object, the ratio of the transmitted power to the incident power and is the reflectance of object surface, the ratio of reflected power to the incident power.

8 If we consider the opaque ob-jects only, then = 0, and from an equation (1) it follows: = 1 (2)Since the absorption cannot be greater than unity, the ab-sorbed power is maximal for the perfect absorber, the so-cal-led black body. For worse absorbers, the absorption is lower that 1. At the thermodynamic equilibrium the power radiated from the unit area of radiating body must be equal to the power absorbed by the same area unit. For the characteri-zation of the radiating properties of real bodies, we use an emissivity (T), which is generally the ratio of power emitted by the unit area of real object to the power emitted by the unit area of black body.

9 Provided the opaque object ( = 0) is in thermodynamic equilibrium, we get: (T) = (T) (3)Equation (3) is the consequence of Kirchoff s law of thermal radiation [1]. For the black body the value of is equal to 1. In accordance with Lambert s law, the radiant intensity I from small area element dA depends on the cosine elevation angle , I = In cos . Intensity I is the radiant power (ra-diant flux) d emitted by a source into a solid angle d , : Z) dId .Radiance L is defined as the radiation power emitted by the area element dA of the source into the solid angle element d in the given direction (see Fig.

10 1). It follows: 2cos cosdIdLd dAdA--Z--) (4)For cosine sources (diffusive surfaces), the radiance L = Ln, the radiance is independent on the direction in which it is measured. This is well-known Lambert s law. Although Lambert s law is a good approximation for many technical sources, there are many surfaces for which equation (4) is not valid, the radiance varies with angle . The normal emissivity n(T) is usually used in practical applications. The n(T) is a ratio of radiance Ln of the real radiant source in normal direction to the radiance Lo of the black body (the INFLUENCE OF GONIOMETRIC ARRANGEMENT AT THE CONTACTLESS TEMPERATURE MEASUREMENTJ n Bartl, Vlado Jacko, Roman F raAbstractWhile performing some technological operations, coupled with the contactless temperature measurement, e.
